{"product_id":"dc-jistic-geya-gym10-dc-2p-c20a-4-5ka","title":"GEYA GYM10-DC 2P C20A 4.5KA DC circuit breaker","description":"The GEYA GYM10-DC 20A double-pole DC circuit breaker is a specialised protective device designed exclusively for direct current (DC) circuits with a maximum operating voltage of up to 500 V DC. It is primarily intended for protecting individual strings of photovoltaic panels, DC inputs of inverters, battery systems and DC power distribution networks.\u003cbr\/\u003e\u003cbr\/\u003eUnlike standard AC circuit breakers, it features a special arc-quenching chamber and permanent magnets adapted to quickly and reliably extinguish the direct current electric arc that occurs when a circuit is opened under load or during a short circuit.\u003cbr\/\u003e\u003cbr\/\u003eThe device features non-polarised or clearly marked polarity (depending on the connection) and ensures reliable disconnection of both poles (+ and -) in a DC circuit. The rated breaking capacity of 4.5 kA provides a sufficient safety margin for photovoltaic installations and DC switchboards.\u003cbr\/\u003e\u003cbr\/\u003eMAIN ADVANTAGES AND APPLICATIONS:\u003cbr\/\u003e\u003cbr\/\u003eSpecifically for photovoltaic systems and DC circuits: Designed for DC voltages up to 500 V DC.\u003cbr\/\u003eTwo-pole design (2P): Ensures safe disconnection of both the positive and negative branches (L+ \/ L-) of the DC circuit.\u003cbr\/\u003eRapid DC arc quenching: The integrated magnet-assisted quenching chamber prevents the electric arc from burning out upon disconnection.\u003cbr\/\u003eReliable protection for PV strings: Protects solar panels, charge controllers and DC cabling against overcurrent and short circuits.\u003cbr\/\u003eVisual contact status indicator: A clear window on the front panel indicates the device’s status (red = on \/ green = off).\u003cbr\/\u003eStandard modular width: Available in a 2-module width (36 mm) with simple mounting on a DIN rail (TH35).\u003cbr\/\u003e\u003cbr\/\u003eELECTRICAL AND TECHNICAL SPECIFICATIONS\u003cbr\/\u003e\u003cbr\/\u003eBrand \/ Manufacturer: GEYA\u003cbr\/\u003eModel series: GYM10-DC\u003cbr\/\u003eDevice type: Direct current modular circuit breaker (DC MCB)\u003cbr\/\u003eNumber of poles: 2P (two-pole)\u003cbr\/\u003eRated current (In): 20 A\u003cbr\/\u003eRated operating voltage (Ue): 500 V DC\u003cbr\/\u003eRated short-circuit breaking capacity (Icn): 4.5 kA (4,500 A)\u003cbr\/\u003eBreaking characteristic: C (designed for DC circuits)\u003cbr\/\u003eElectrical life: \u003e= 1,500 cycles\u003cbr\/\u003eMechanical life: \u003e= 8,500 cycles\u003cbr\/\u003eMounting: On DIN rail (TH35)\u003cbr\/\u003eProtection rating: IP20\u003cbr\/\u003eHousing material: Self-extinguishing plastic UL94 V-0\u003cbr\/\u003eOperating temperature: -20 °C to +70 °C\u003cbr\/\u003eCertifications and standards: CE, RoHS, IEC\/EN 60947-2","brand":"GEYA","offers":[{"title":"Default Title","offer_id":55329629077842,"sku":"04291303","price":195.0,"currency_code":"CZK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0954\/9624\/1490\/files\/04291303.jpg?v=1793774962","url":"https:\/\/tipa.eu\/en\/products\/geya-gym10dc-2p-c20a-4-5ka-dc-circuit-breaker","provider":"TIPA","version":"1.0","type":"link"}
